摘要
引入分形理论、岩石损伤力学和岩石断裂力学等相关领域的最新研究成果,综合采用理论分析、试验研究和数值分析等手段,主要对油气藏水压裂缝的分形特征、水力压裂裂缝起裂延伸的损伤力学模型和裂缝几何形态模拟的损伤力学模型等方面进行分析研究,力图对上述水力压裂力学机理研究中关心的问题进行深入细致地理论分析与探索,分析了相应的力学模型和计算方法,并进行了探索性的算例分析,为水力压裂力学机理的研究提供了新的方向和新的思路。
The newest researches of factual geometry, damage mechanics and rock failure mechanics are introduced into the researches of hydraulic fracturing mechanics. In this thesis, with theoretical, experimental and numerical approach, fractal features of fracture, failure mechanics models of fracture propagation and fracture geometry modeling are studied, and relative mathematic models and its effective computing methods are analysed, Moreover, some samples are given to testify and analyze these models and methods. It applies some new ideas to study hydraulic fracturing mechanics.
